I think your confused. "Deck" refers to the height of the deck surface (head gasket) from the crankshaft. There are tall deck and short deck m119s. If I remember correctly, the early m119s (with mechanical fuel injection) are tall deck. A design holdover from the m117. The later (post 92 yr.) m119s were all short deck engines.

Open deck and closed deck refers to the construction of the block at the head gasket surface. Closed deck blocks have a solid surface that makes the block more rigid and stronger. A small block Chevy or ford had a closed deck. Open deck block you can see the physical bores and the coolant passages around them. Most Honda engines are open deck.

I think all m119 tall deck (early cis engines) are closed deck. The later motors came both ways, probably as a cost cutting measure. I think 1993 was the switchover year from closed to open deck.

Hope it helps.
